TL;DR

This paper explores non-supersymmetric orientifold field theories derived from brane configurations, examining their gauge/gravity correspondence and perturbative behavior in the large N limit, revealing Bose-Fermi degeneracy.

Contribution

It introduces brane-inspired orientifold field theories with common bosonic sectors to super Yang-Mills and analyzes their gauge/gravity duality properties.

Findings

Perturbative behavior matches closed string channel predictions at large N.

The theories exhibit Bose-Fermi degeneracy in the large N limit.

Gauge/gravity correspondence can extend to non-supersymmetric theories.

Abstract

In this paper we consider the gauge theory living on the world-volume of a stack of N D3-branes of Type 0B/\Omega' I_6(-1)^{F_{L}} and of its orbifolds C^2/Z_2 and C^3/(Z_2 x Z_2). The gauge theories obtained in the three cases are a brane realization of ``orientifold field theories'' having the bosonic sector common with N=4,2,1 super Yang-Mills respectively. In these non-supersymmetric theories, we investigate the possibility of keeping the gauge/gravity correspondence that has revealed itself so successful in the case of supersymmetric theories. In the open string framework we compute the coefficient of the gauge kinetic term showing that the perturbative behaviour of the orientifold field theory can be obtained from the closed string channel in the large N limit, where the theory exhibits Bose-Fermi degeneracy.
